BUFFIN'G-MACHINE.

To all whom 'it may concern:

'Be it known that I, HARRY J. BREWER, a citizen of the United States, and a. resident of New York, inthe county of New York and 6 State of New York, have invented a certain new and useful Improvement in Bufling- Machines, of which the following is a specification.

Thisinvention relates to means for polishr'buffing round or tapering metal, or arts, suchas the plugs or jacks used aphy and telephony, the object of entionbeing to provide a durable and rent device, simple and compact in con *struction'.

The invention consists in features of construction and combinations of devices hereinafter described and more particularlyset forth in the appended claims.

One form of the invention is illustrated in the "accompanying 'drawing, forming part hereofiin which Figure 1 is a side elevation; Fig. 2 is a front elevation of the carrier; and Fig. 3 is a section of a modified form of holder.

In the drawing, the reference letter a designates an electric motor of any approved type'or construction, and b denotes the rotary shaft thereof. Or other means for drivi the shaft 1) may be used. On the shaft a buffing, grinding, ,or polishing wheel'd is made fast in any suitable manner, as by innin its hub 15 to the shaft. The

wheel (i may e made of any construction or 85 material suitable to the purpose in view, or it may be coated, charged, or impregnated with any such substance.

Mounted on the shaft 1) to rotate indeendently thereof is a disk or carrier e, which 40 is held in place on the-shaft in any suitable manner, as by a nut f on the shaft 1). The carrier 0 preferably has a radial slot 9 therein to receive a tube and the tube It is locked sition by nuts '1'. thereon, which engage Specification of Letters Patent.

k may be' double, one tube being locked against rotation by the nuts 4'. while the other, or inner, part may rotate therein; see it, h, Fig. 3.

In the use of the invention, the plug or jack h is thrust through the tube into conwith the periphery of the buffing wheel, and the carrier is then given one or more turns .on its axis while the operator holds the lug or jack from turnin whereby every part'of the surface of the ug or jack is resented to theaction of t 1e rotating bu ing wheel and receives a polish from the action thereof.

The above described device provides a sincilple and efficient means for polishing jacks plugs, and may be readily carried about and e used to re olish jacks or plu s in central offices as we as in the works w ere such are made.

set up so that the tube What I claim as new and desire to secure by Letters Patent of the United States is 1. In a buffing device, a bufiin wheel and a carrier independently rotata le on the same axis, and a jack or plug holder on the carrier.

2. In a bufling device, a buffing wheel and a carrier on the same axis but rotatable independently of each other, and a jack or plug threads on the outer surface thereof.

older on the carrier, with means for ad usting the position of the holder toward and from said axis. "Signed at New York city in the county of New York and State of New York this29 day ofMarch A. D. 1907. Q
